The specific heat capacity of liquid water is 4.186 J/gm K. This means that each gram of liquid water requires 4.186 Joules of heat energy to raise its temperature by one degree Kelvin. One molar mass of water is equivalent to 18 grams. Therefore, the molar heat capacity becomes the product of 4.186 and 18
The correct option is 3.
In the presence of oxygen, iron will react with water to form rust. This is a chemical reaction and it is one of the chemical properties of iron.
Chemical properties refers to those properties of a substance, which can be used to identify it chemically, that is by reason of chemical reactions. Examples of chemical properties are reactivity with water, heat of combustion, electromotive force, pH, etc.<span />
